AmateurLogic 218: No Static At All

Major elimination of static and noise in HF radio reception using neural networks and machine learning. Sodium ion battery tests. Hurricane season preparation. This episode of AmateurLogic (Episode 218) focuses on emergency preparedness, cutting-edge radio technology, and battery testing. The hosts, George, Tommy, Emile, and Mike, discuss the following topics: Neural Networks for Noise Reduction (21:34 - 34:18): George explores using AI-powered noise suppression (RN Noise and RM Noise) on a Raspberry Pi 5 and Windows to eliminate static and interference, significantly improving audio clarity on HF bands. Battery Testing (6:16 - 18:14): Tommy tests sodium-ion batteries using a ZK Tech EBC A20 load tester, noting concerns regarding their discharge curve and practical usability compared to standard lithium-ion batteries. He also discusses a great deal on LiFePO4 batteries found at batteryhookup.com (1:00:44). Emergency Preparedness & Hurricane Season (18:14 - 21:27, 50:00 - 59:13): With hurricane season underway, Emile demonstrates his go-kit setup, drainage checks, and the use of WinLink for sending messages via HF radio when local infrastructure is compromised. News & Community (47:29 - 49:47, 1:04:31): Mike highlights the upcoming cessation of the CHU Canada time signal broadcasts on June 22nd. The team also reminds viewers about Field Day (June 27-28) and encourages community engagement through AmateurLogic social channels.
